Android cross-platform arm64 app build failed

[ISensuiI]

Problem:

I am building an Android app using rust as the core. It needs to compile the aarch64-linux-android core for kotlin to call. I configured various environment variables and used the https://github.com/ianthetechie/uniffi-starter sample code to build. It was easy to compile the sample code for multiple cores including x86, x86_64, armv7, arm64v8a, and successfully call it through kotlin. This at least proves that there is no problem with my win11 environment. (I put the win environment system variables and logs below.)

When I compiled, I encountered the problem of not being able to compile. At first I thought it was my environment problem. I reinstalled vstool and clang. The same error. I added ninja to handle the compilation, but the problem remained. Finally, I installed rocky linux 9.5 through the virtual machine. And configured the sdk ndk. The problem still exists, clang: error: unsupported argument 'armv7-a' to option '-march='. The specific reason is unknown. I can't determine this armv7 Where did the parameter appear? I tried to clean the environment variables in linux/win and reset them (I put them below), but they didn't work. But if there is a problem with my win environment, uniffi-starter should have the same problem.

When I compiled,
uniffi-starter + cargo_ndk was completely fine
My Iroh project + cargo_ndk | cargo build (native compilation + environment.sh configuration file)
all had the same error, so I also ruled out the cargo_ndk problem. Only aws-lc-rs is left. I tried adding debugging information to the project builder/cc_builder.rs and supplementing Cmake parameters, but none of them worked. I am not familiar with cmake.

I understand that it is not an internal problem of iroh, but a dependency problem of rustls. However, iroh has clearly stated that it supports mobile terminals including iOS and Android. According to my understanding, it should be easy to compile. But I still can't solve it.
I have checked that rustls encryption methods include aws-ls-rs and ring, but I don't know if they are fully compatible, so I didn't try it easily.

Since these are my core dependencies, I can't replace them. I spent about 2 days without any progress. I am not sure if I used it wrong or if there is a problem with the project itself. Please give me some help. Thank you very much.

Hm, I'm far from an expert on compiling stuff to android. I know that DeltaChat folks keep doing this just fine.

One thing I can tell you is that you shouldn't need aws-lc-rs in your dependency tree. So if you have problems getting aws-lc-rs to compile to android, you can get rid of it.

I see you've looked at cargo tree -i aws-lc-rs. To dig deeper, you can call cargo tree -i aws-lc-rs -e normal -e features, to get an overview of which features of which dependencies end up pulling in aws-lc-rs. Good luck!

Copying libraries to E:\WWW\Rust\A\client\rust\ffi-core\jniLibs
PS E:\WWW\Rust\A\client\rust\ffi-core>

It succeeded. Thank you very much for your reply. Your reply reminded me. I wrote down the reason for others to check.

The cause of the problem is still the rustls library. It will enable the aws-lc-rs library feature by default. Although ring has been added, it will still enable aws-lc-rs because it is not turned off by default. When I checked the dependent libraries before, I saw that iroh-goss iroh dns also depended on rustls, but rustls was turned off by default, and iroh related libraries were turned off by default.
rustls = { version = "0.23", default-features = false, features = ["ring"] }

This made me mistakenly think that iroh also depends on aws-lc-rs. After matheus23 reminded me, I cloned a new iroh and used cargo tree -i aws-lc-rs -e normal -e features to check and found that iroh did not have any aws-lc-rs dependencies by default.

After I checked the rustls manual It was found that it would be introduced by default.
The dependencies are as follows. After modification, use again
cargo tree -i aws-lc-rs -e normal -e features
Get not found.

Compile again, everything is normal.
reqwest = { version = "0.12.14", default-features = false ,features = ["blocking","rustls-tls"] }
rustls = { version = "0.23.23" ,default-features = false,features = ["ring"] }
